Fracturing fluid cost and environmentally friendly use of natural gas

Natural gas used for hydraulic fracturing is said to be in American breakthrough, shale gas has low cost, but the domestic cost but has not closed, what reason be? A bossinadvertently say one of the mysteries of. Fracturing fluid is the main cost of shale gasis said to account for more than 70%, and the main component in the shale gas fluidssuch as sodium salicylate and quaternary ammonium salt, sodium salicylate salicylic acid if not made of raw materials or without high level such as pharmaceutical grade,the intermediate process of sodium salicylate as raw material for the production of salicylic acid in phenol water crude sodium salicylate the solution of sodium salicylate,take this cost can be greatly reduced by at least half or even below 40%, however at the cost of the crude sodium salicylate containing 2-3% phenol toxicity great. Thisleads to two problems, one is USA really with crude sodium salicylate as fracturing fluid (maybe it can oppose shale gas from USA environmentalists and proposed the pollution of fracturing fluid containing phenolic evidence), this can be from the exportstatistics or manufacturers such as the biggest foreign trade personnel than domestic manufacturers to understand, two is the 2-3% of phenol will be diluted to what extentas to whether the trace phenol also has the role of sterilization effect of 2-3% relative to the groundwater quality can be ignored or even play a positive role in the pollution of water resources, the domestic serious groundwater pollution serious situationdecision is difficult. So, the oil well fracking fluid cost can be greatly decreased by more than half, the key is to consider the influence of environmental protection.
